In this work, Dr. Paul Brown focuses on arms control issues starting with the Eisenhower administration through the signing of the Comprehensive Test Ban Treaty by President Clinton and the failed ratification of the Treaty. In particular, the book explores the issues related to the need for nuclear testing and the efforts that would eventually bring about the test moratorium and the creation of the Stockpile Stewardship Program as a result of U.S. policy actions in light of the changing geopolitical and technical drivers and constraints. Paul’s history provides a perspective on how the issues surrounding nuclear testing evolved, with an emphasis on Lawrence Livermore’s participation over the years.
